Interaction with processor sets
Dynamic nPartitions is fully integrated with processor sets. If the attributes of a processor set are
established so that it is not allowed to become empty, then the last SPU in that processor set cannot
be online deactivated. If a cell online deactivation operation would cause the processor set to
become empty, then that operation will not complete successfully.
Cell reset recovery time
When a cell is deactivated online, it is reset to prepare for its next use. The reset operation does a
full initialization, so it takes approximately 1 minute. During this time the cell can not be reactivated
nor assigned to another partition. During the reset recovery time, parstatus shows the state of the cell
as "Powering on".
Summary
Dynamic nPartitions operations complete the value proposition of partitionable server complexes.
Vast flexibility can be realized through changing the composition of nPartitions while continuing to run
their application workloads. Many real-world scenarios can benefit from timely use of Dynamic
nPartitions. Advance planning in the configuration of the system complex can maximize the benefits
of Dynamic nPartitions functionality.
